The premarket selloffs in the shares of Apple Inc. , Boeing Co. and United Technologies , which all reported quarterly results, can be blamed for all of the 74-point drop Dow industrials futures ahead of Wednesday's open. Apple's stock slid $3, or 3%, to $96.99 in premarket trade, which would shave about 21 points off the price of the Dow Jones Industrial Average , after the technology giant reported late Tuesday fiscal first-quarter sales that missed expectations. Boeing's stock tumbled $8.51, or 6.6%, to $119.50, which would cut the Dow's price by 58 points, after the aerospace giant provided a downbeat 2016 outlook. United Technologies' stock dropped 85 cents, or 1%, to $84.80, which would lower the Dow's price by 6 points, after the industrial conglomerate missed fourth-quarter sales expectations by a wide margin.
